Net Metering in Massachusetts: How It Works in 2026

In Massachusetts, net metering credits solar owners for surplus electricity sent to the grid. Residential systems of 25 kW AC or less are exempt from net metering cap allocation. Massachusetts also exempts solar equipment from the 6.25% sales tax. The SMART program pays a flat $0.03 per kWh for small residential systems in 2026.

Net metering represents a pivotal aspect of solar energy policy in Massachusetts, allowing homeowners and businesses to offset energy costs by generating their own electricity through solar panels. This practice not only reduces reliance on traditional utility sources but also generates surplus energy credits that can be applied against future electricity usage. As the landscape of net metering evolves, especially with anticipated changes in 2026, it is essential for consumers to understand how these regulations will impact their investments in solar energy and contribute to overall savings. In this comprehensive guide, we will explore the mechanics of net metering, key regulations, the SMART program, financial impacts, and the latest updates to ensure that solar customers in Massachusetts can maximize their benefits.

How Net Metering Works

Net metering is a billing mechanism that allows solar energy system owners to receive credits for the energy they generate and feed back into the grid. When a solar panel generates more electricity than a household consumes, the excess energy is sent to the grid, and the customer receives a credit that offsets future electric bills. This credit system typically operates on a one-to-one basis, ensuring fair compensation for solar energy producers. As net metering policies continue to evolve, understanding these mechanics is crucial for potential solar energy users.

How Net Metering Works in Massachusetts

Utility Variations

Different utility providers in Massachusetts may have varying regulations regarding net metering. In National Grid towns like Rehoboth, one utility handles your interconnection and net metering account. For example, Eversource and National Grid have distinct policies about credit allocation and system size that solar customers must consider when setting up their installations. These variations can significantly impact the overall efficiency and financial return of a solar energy system, and a town like Wareham, served exclusively by Eversource, has just one utility to coordinate.

System Size Limits

Massachusetts imposes specific limits on the size of solar systems eligible for net metering. Residential customers typically have lower capacity thresholds compared to commercial entities. Understanding these limits is essential to ensure compliance and optimal use of net metering benefits.

Credit Duration

Credits generated through net metering can be carried forward to offset future energy usage, but there are time limits associated with this rollover. Staying informed about these timelines ensures that solar customers can effectively manage their credits to maximize savings.

SMART Program and Net Metering in Massachusetts

The Solar Massachusetts Renewable Target (SMART) program complements net metering by offering additional financial incentives for solar energy production. This program includes fixed payment structures designed to promote solar investments in the state. Specific incentives are available for systems that integrate energy storage solutions, making the SMART program an attractive option for those looking to optimize their solar power systems.

Financial Impacts of Net Metering in Massachusetts

Analyzing the financial implications of net metering is critical for potential solar energy adopters in Massachusetts.

Electricity Bill Savings
